Global Warming

Amazon Adds to Global Warming

The first broad study of all greenhouse gases in the Amazon rainforest reveals that on balance the damaged ecosystem is now a net contributor to climate change. Part of the problem comes from local damaging activities like logging, dam-building, and cattle ranching. But planet-wide warming is also disrupting the water cycles in the Amazon, intensifying floods and drought that create more greenhouse gases and further decrease the ecosystem’s ability to capture and store carbon emissions.

Wildfires

US wildfires cause mass bird die off

After an abnormally large number of migratory birds turned up dead in people’s backyards in Colorado and other parts of western and central U.S. states.

Around the same period as the birds’ deaths, more than 3 million hectares (7.8 million acres) of land burned, which resulted in habitat loss and the emission of toxic compounds that threaten the health of both avian species and humans. In addition, snowstorms struck parts of the Northwest in early September while these birds were in the midst of their annual migration. Some areas experienced temperature drops of as much as 40°C (72°F) in just a few hours.

Researchers found that the wildfires and also the toxic air were the two factors that influenced the birds’ mortality. There was a strong correlation between the observations of dead birds and wildfires and the toxic gases they produced, but there was not enough information to conclude that the avian mortality was connected to the early winter storms.
